Willia Eraanberg Patented Nov. 1, 1932 UNIE'E7 WILLIAM GREENBEB-Gr, F PHILAQELIPHIA, PENNSYLVANIA, ASSIGNOR TO FISCHMAN & SONS, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA INSULATING COLLAR/FOR ICE CREAM. CABINETS Application filed November 26, 1929. Serial No. 409,922.

This invention relates to improvements in soda fountains or cooling cabinets, and has particular reference to the provision of an improved insulating collar or so-called breaker strip which isv used in the cooler box or fountain Construction at the top of a cooling compartment for the purpose of breaking the metal-tdmetal contact between the top capping and the lining ofthe cooler box.

A further object of this invention is the provision of an improved insulating collar arranged in an eflicient and protected relation in a soda fountain or cooler box construction over a compartment which is adapted to receive a plurality of ice-cream cans or other containers, through which a dispenser may reach for quick and convenient access to either of the cans without liability of personal injury, or injury to the collar or other parts of the fountain structure' 7 A further object of this invention is the provision of an improved capping structure for soda fountains, cooler boxes and the like, provided with an opening therethrough above the ice-cream or other compartment, which flares downwardly into the compartment with an increasing dimension, particularly in the direction of the front of the fountain, in order that convenient access may be had to the foremostof a plurality of cans or other receptacles below the opening. A further object of this invention is the provision of an improved insulation collar for the openings in cappings of soda fountains and the like, which is preferably cast in one piece and defines an oval opening; the end of which facing the front of the fountain is flared downwardly to increase the size of the opening.

A further object of thisinventionjis the provision of improved means for protecting the. lower edges'of' insulation fountain cappin'g collars frombeing damaged as an incident of contact with dippers and thelike.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

It is: highly desirable to manufacturesoda fountains which are relatively narrow, and yet which will contain all of the essential details and units. The length of a fountain may of course be arranged to suit, and the height of soda fountains are substantially fixed. However, the width, that is from front to rear, should be as small in dimension as possible,

because of the saving in -material and economy 'in manufacture; to facilitate and expedite production because of the ease of handling during manufacture; toenable compact storage, and ease of installation through narrow doorways and the like, and most important, to expedite service because all units of the narrow fountain are within easy reach of the dispenser. WVith'wide soda fountains the dispenser must necessarily lean over andreach farther for syrups, soda water, etc. and this not only tires the dispenser, but slows up service considerably. With the narrowness of the fountain as a dominant characteristic, and bearing in mind that soda fountains must receive quite a number of. ice-cream cans and containers, the present construction requires that the syrup rack slightly overhang the ice-cream can com- The fountain as shown may generally be,

designated by the letter A, and it includes a base supported as bylegs 11, and it is provided with upstanding walls 12'at the front, rear, and ends thereof, of any approved material. A counter 14' is provided at the top of the front wall structure of the fountain,

and just rearwardly below the counter 14in disposed the supportingstructure 15 of the capping B'for receiving'thejars 17 adapted to receive syrups and fruits The cabinet structune of the fountain receives therein brine tanks 20, and suitable metal liners 21,

the side walls of which are spaced. therefrom forreceiying the circulating brine. The tank 20 and its linerv 21 9f course terminate immediately below; the capping B, as is the case inzconventional practice, and the liner 21 defines therein a compartment 25 ,vhich in cross section is elongated from front to rear of the fountain and adapted to receive front and rear cans or containers 2? and 28 respectively. The cans or containers mayreceive ice-cream, as is'usual, or may receive any other substances desired.

The capping B includes the metal top wall 30 which-extends aboutand forms part of the .jar rack or support 15 andwhich extends to the rear wall 12 of the fountain where it is detachably connected. It: includes the insulation cork or other filler 31 and the insula tion lining 32, preferably of, hard rubber,

synthetic resin, or the like. Openings are provided therethrough lined with the improved insulation collars, C.

n The insulation collar C may be made of a synthetic resin, although preferably, for purposes ofeconomy, it is constructed of hard rubber. It extends from the top of the metal receptacle liner 20 through the thickness of the capping B to the top thereof, and serves to break the metalto-metal contact between the metal liner and the metal top wall of the capping, all of which-prevents condensation of moisture externally uponthe capping or the closures overthe opening through the collar, as has been well understood in this art for many yea-rs. It is'to be particularly noted that the opening d0 which receives the collar C 7 lies substantially flush with the vertical rear of the metal liner 20, and eXtends therefrom forwardly, terminating short of the H frontof the metal liner 20, as shown in Figure, 1, and overhangs onlya rear portion of the front ice-cream can 27 ,when positioned in the chamber 25. r p

The collar C is of band-like material of portion 49 and therefrom the remaining offlcourse be provided for any approved height, and the material thereof is relatively thin. It includes the side wall portions and 46, substantially parallel, and the arcuated rear end wall 47. The portions 45, 46, and 47 are all of the same height. The opposite end wall of the collar is provided with an upper arcuated relatively short portion, 50 of this end of the collar C flares divergently downwardly with a sort of visor effect, for the purpose of increasing the size of the opening through the collar C at the forward end. That is, the length of the opening 51- throughthe collar G is less at the top of the collar where it opens onthe top of the capping B, than at the bottom of the collar where it opens into the chamber 25; the increase in size being all at the front end of the collar C forthe-purpose of enabling an easy access to the can 27, as will be perfectly apparent. The upper marginal-portion49, and the other upper margins entirely,

about the collar C are received in beading 55 formed in the metal top wall 30 of the cap.- ping-B for the purpose of providing an effective joint and anchoring the collar C in place.

'The collar C is of less'vertical height at the forward end, that is, the lower edge at 55 terminates flush withthe lower surface 32 of the capping, whereas thelower edge56 along the sides and rear of the collar G terminates at a lower level into the chamber 25, as can readily be seen from Figure l ofthe drawings, The edges 5.5 and 56 are convexly arcuated, as shown clearly at in Figure 6 of the drawings, so that'no sharp edges or corners are presented to'the compartment 25. This prevents to a. great extent the chipping ofthe shoulder as an incident of contact with metal parts, such as I dippe'rs, and prevents injury to an operators armor hand should itcOntact therewith. I As a furtherexpedient in preventing damage to the rear and sides of the collar, especially surrounding the rear can 28, the metal liner 21 is conveXly beadedat 70, bulging into the compartment 25 at the top thereof immediately below the lower edge of the rear end and adjacent sides of the collar C, as a rprotectionfor the lower edge of-the. collar at these locations. This beading not only prevents injury to the collar by warding-off dippers, but it .prevents the cans, as they are lowered or removed'with respect to the chamber 25,. coming directly in contact with the lower portion of the collar.

,Any approved type of: closure means may I shutting off'the opening through the-collar. In the present instance Iprovideapair of hingedly connected insulated closure lids 7 5 and-7 6, hingedly connected at.77 on a linecat right angles to the major axis of} the opening. through thecollar. C,Vat a location;midway between.

the ends of the opening through the capping.

stood by those These lids 7 5 and 7 6 are provided with handles or knobs 79 for the respective swinging thereof as a means of securing access to I the cans 27 and 28, as will be readily underskilled in this art.

Ihe means of mounting the closure lids is preferably disposed at the axis or pivot axle 77, and preferably comprises a detachable supporting rail or gutter 80, supported at the ends thereof by means of suitable supporting brackets 81 which are secured in the capping beneath the metal wall 30 thereof, and extend into the area at opposite sides of the opening 40; the collar C in the opposite walls l5 and 46 thereof being downwardly notched, as shown at 85 in Figure 2 of the drawings to accommodate these brackets.

From the foregoing description of this invention it is to be seen that an improved substantially oval-shaped insulation capping collar for soda fountains has been provided, which is particularly well adapted to insure an easy access to both containers of the two can ice-cream containers of a soda fountain,

together with a conservation in space and bulk of the fountain. While these collars may be formed in strips and subsequently shaped, they are preferably cast integral, eliminating any appearance of seams. The inside surface is polished and of course the bottom edges are rounded and smooth as mentioned.

Various changes in the shape, size, and arrangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the scope of the claims.

I claim:

1. As an article of manufacture an elongated insulation collar for use in defining an access opening to the compartment of a soda fountain or cooler cabinet, of band-like insulation material having an elongated opening therethrough, the collar being flared divergently downwardly to increase the size of the opening from the top of the collar towards the bottom thereof.

2. As an article of manufacture an insulation protecting collar for use in the access openings of refrigerated containers formed of rigid insulation material being relatively shallow in thickness and having considerable depth, said collar being elongated to define an elongated opening therethrough, the collar at one end being flared downwardly divergent with respect to the other end to increase the size of the opening from the top edge of the collar downwardly.

3. In a soda fountain capping the combination of a metal top having relatively thick insulation material secured therewith and having an elongated transverse opening therein, and an elongated insulation collar in the opening having an elongated opening therethrough, said opening increasing in size from the top of the capping in the direction of the bottom thereof.

4:. In sodafountain structures the combination of a cabinet-like body having a metal tank therein defining an upwardly opening compartment, a removable capping having an opening as access to said tank, an insulation collar surrounding the opening in the capping, the collar being relatively high and shallow in thickness, closure means for the opening to the collar of the capping, and means formed on the top of said tank and overlapping beneaththe lower margin of said collar for protecting the same against injury by reason of articles through to said tank. I

5. In a soda fountain the combination of a cabinet including a compartment having insulated surrounding bottom, side, end, and top walls, the top wall having an opening therethrough of less horizontal cross area than the horizontal cross area of the adjacent part of the compartment, and an insulation collar mounted in said top wall surrounding said opening throughout its depth and having an opening flaring from the top edge of the collar in a divergent relation to substantially the bottom edge of the collar increasing the size of the opening from the top of the top wall toward the bottom of the top wall.
